The study found that SARS-CoV-2 underwent little significant genetic change in the first year of the pandemic, suggesting a 'generalist' nature and rapid transmission. This is attributed to human population immunity and lack of containment, allowing the virus to spread quickly.
Researchers found that neutralizing antibodies from COVID-19 vaccines are less effective against new variants, including those from South Africa and Brazil. The study suggests that mutations in the spike protein may contribute to the variants' resistance.
A study published in PLOS Medicine found that HPV vaccination for men and women over 26 years has limited health benefits and is not cost-effective. The study used two mathematical models to simulate HPV infection and cervical cancer, as well as six non-cervical HPV-related cancers and genital warts.
A phase 1 study found that a single dose of Ad26.COV2.S vaccine induced both antibody and cellular immune responses. The vaccine is currently being tested in two phase 3 clinical trials to determine its efficacy against COVID-19.
A new study identifies specific job categories that put workers at risk due to close contact with others. Black workers are especially overrepresented in indoor jobs, while Hispanic workers are overrepresented in outdoor high-proximity jobs.

Researchers at Mount Sinai found that a single shot of COVID-19 vaccine can provide immunity to individuals who have previously been infected by the virus. This could help stretch limited vaccine supplies and spare individuals from unnecessary side effects of a second dose.
Early commercial batches of Pfizer-BioNTech's COVID-19 vaccine had lower than expected levels of intact mRNA molecules, a finding that raised concerns about the manufacturing process and its impact on vaccine potency. Regulators like the EMA and FDA are unsure of the implications for safety and efficacy.
A new study by Norwegian University of Science and Technology highlights how new technologies can exacerbate existing social health inequalities. Research shows that people with lower education and income have poorer health outcomes, and that wealthier individuals may buy their way to access to life-saving vaccines.
A Princeton University and McGill University study found that delaying second COVID-19 vaccine doses reduces case numbers in the short term. However, longer-term case burden and potential viral escape from immunity may depend on the strength and duration of immune responses generated by natural infections or one to two vaccine doses.
A study using real-world data from employees at Mass General Brigham found that the incidence of anaphylaxis was higher than CDC estimates, but still extremely low. The majority of cases recovered without serious complications.
A new modeling study examines the impact of one versus two doses of a COVID-19 vaccine on infections and immune escape. The study finds that while one-dose strategies may reduce short-term infections, weak immunity could lead to long-term virus replication and mutation.
A new poll by Michigan Medicine shows a significant increase in COVID-19 vaccination enthusiasm among older adults with high risk of severe illness.

The authors call for coordinated action to protect these vulnerable patients. Many countries do not mention mental health in their vaccination priority guidance, leaving patients at risk.
Experts discuss the ethics of criminalizing false vaccine information. Melinda Mills argues that deliberate intent to spread malicious disinformation should be considered criminal due to preventable deaths. Jonas Sivelä believes this approach may not address underlying issues like vaccine hesitancy and lack of trust in institutions.
A new study suggests that vaccinating all babies on the day of birth with BCG could reduce neonatal infections and death in areas with high infectious disease rates. The results also increase the possibility that the vaccine might be used to protect children and adults against COVID-19 and other new infectious diseases.
The US and UK's large vaccine stockpiles are morally reprehensible, argue experts, as poor countries face years of vaccine scarcity. Rich nations should prioritize global access to COVID-19 vaccines to respect human rights and reduce the pandemic's spread.
